Based on J A Motyer. The passage declares that the Jews are God’s proof of His existence and purpose.
A. The court assembled
8 Bring forth the blind people that have eyes,
and the deaf that have ears.
9 Let all the nations be gathered together,
and let the people be assembled:
B. The issue announced
who among them can declare this, and shew us former things?
let them bring forth their witnesses, that they may be justified:
or let them hear, and say, It is truth.
C. YHWH’s witnesses
10 Ye are my witnesses, saith the LORD,
and my servant whom I have chosen:
that ye may know and believe me,
and understand that I am he:
C’. YHWH’s claim
before me there was no God formed,
neither shall there be after me.
11 I, even I, am the LORD;
and beside me there is no saviour.
B’. The issue settled
12 I have declared, and have saved,
and I have shewed, when there was no strange god among you:
therefore ye are my witnesses, saith the LORD, that I am God.
A’. The verdict
13 Yea, before the day was I am he;
and there is none that can deliver out of my hand:
I will work, and who shall let it?
